He should let someone else rebuild Qantas.
With the competition from middle east carriers, high fuel prices, QF Sale Act, and relatively high labour costs in Australia (irrespective of unionised or not), who says a rebuilt Qantas is going to be more successful, or even successful full stop? I really think QF's problems stem from well before AJ, living off the spoils of a cosy duopoly in US routes and near monopoly in corporate domestic market for way too long. That and having no 777s. I'm no expert, but I don't think there's an easy fix - even with abundant capital and more focussed management.
Having said that, some of the things we've seen strategically from AJ/QF just seem on the face of it plain daft.
